ELECTRICAL AND IGNITION
Install the electrical harness base and secure with four screws. Torque screws to 60 to 84 in. lbs (7 to 9.5 N·m).
- Harness base screws
Reconnect the stator connector, two port side trim system connectors, port engine temperature sensor, and the port ground terminal.
Reconnect the crankshaft position sensor, throttle position sensor, air temperature sensor, and oil pump electrical connectors.
Install the EMM. Refer to EMM SERVICING on p. 153.
IMPORTANT: Perform the timing verification procedure after flywheel removal or replacement. Refer to TIMING ADJUSTMENTS on p. 157.
TIMING ADJUSTMENTS
Timing Pointer
The timing pointer must be adjusted to indicate “top dead center” (TDC) of the number 1 piston. This reference to the position of the number 1 pis ton is used to synchronize the electronic timing controlled by the EMM with the mechanical position of the number 1 piston. Use the Evinrude Diagnostics Software program to verify and adjust timing. Refer to the software’s “Help Info” for out board timing verification procedures.
To prevent accidental starting while servicing, remove emergency stop lanyard and disconnect the battery cables at the battery.
IMPORTANT: The pointer on these models has two indicator points. The point labeled “V4” is used for 60° V4 models. The unlabeled point is used for 60° V6 models.

V6 pointer
Turn the key switch OFF and disconnect the battery cables at the battery.
Remove spark plugs.
Rotate the flywheel clockwise to 30° ATDC.
Install Piston Stop Tool, P/N 342679, into the spark plug hole of the number 1 cylinder.
- Piston stop tool
Rotate flywheel in a counterclockwise direction until the number 1 piston contacts the tool. Keep pressure on the flywheel to position the piston firmly against the tool. Mark the flywheel directly across from the pointer. Label this mark “A.”
- Mark A
Rotate the flywheel in a clockwise direction until the piston contacts the tool. Mark the flywheel directly across from the pointer. Label this mark “B.” Rotate flywheel counterclockwise slightly to release tool and remove it from spark plug hole.
Use the cast in markers on the flywheel to calculate the exact center between marks “A” and “B.” Mark and label the center point “C.” If mark “C” and the cast-in TDC boss on flywheel are in alignment, the timing pointer is in the correct location.
If the pointer alignment is NOT correct, rotate the flywheel clockwise to align the mark “C” with the pointer. Hold the flywheel in this position. Loosen the pointer retaining screw and adjust the pointer location to align with the cast-in TDC boss on the flywheel. Tighten retaining screw.

Mark C
Repeat the entire adjustment process to make sure pointer is aligned correctly.
Install spark plugs. Refer to Spark Plug Indexing on p. 160.
Timing Verification
Use the Evinrude Diagnostics Software program to synchronize the mechanical timing of the out board with the electronic timing control function of the EMM.
Timing Adjustment Screen
005148 Perform timing verification after any of the following procedures:
Powerhead replacement
Crankshaft replacement
Flywheel removal or replacement
CPS replacement
EMM replacement
EMM software replacement (reprogramming)
IMPORTANT: Make sure the timing pointer is set and the outboard reaches operating temperature before timing verification is performed.
TPS CALIBRATION
Use the Evinrude Diagnostics Software program to tell the EMM what the throttle position sensor voltage level is when the throttle plates begin to open.
Remove the air silencer.
On the Settings screen of the diagnostic software, click the “Set TPS Calibration” button.
- TPS Calibration button
While holding the throttle plates closed, advance the throttle linkage until it stops. The “Measured TPS Calibration” field on the screen will increase. Click the “Working” button in the software to calibrate the TPS.
Install the air silencer.
Perform TPS Calibration after replacing or adjusting any throttle body or throttle linkage parts.
